using sdk out of yocto

[玉栋郭]

hi everyone ,

I got sdk out of yocto using below commond :

bitbake fsl-image-qt5 -c populate_sdk

and I installed successfully。

but i must specify sysroot for compile app . it looks like :

arm-poky-linux-gnueabi-gcc -o test test.c  -sysroot=/opt/imx6ul_yocto_sdk_20170220/sysroots/cortexa7hf-neon-poky-linux-gnueabi

 i am trying to make it use  no -sysroot . so i specify C_INCLUDE_PATH  but it dosn't work.

can anyone help me?

Hello,

Thank you for writing.

How did you write the C_INCLUDE_PATH?

For example, this is how I wrote the C_INCLUDE_PATH.

C_INCLUDE_PATH=/opt/fsl-imx-wayland/4.1.15-1.2.0/sysroots/cortexa7hf-vfp-neon-poky-linux-gnueabi/usr/include/ (This is for my computer).

And, this is how I am compiling the app.

$CC -o hello hello.c (Again, this is for my computer).

I hope this information can solve your question.

Best Regards,

Diego.
